Why does my Navbar content in Bootstrap not show up when I click the hamburger menu?

Quick question. When I click the hamburger button in bootstrap, the content doesn’t slide down. I was following a tutorial on it, and couldn’t tell what I was missing on this. Am I missing something in the button tag? Everything else is working fine. Any ideas?
Thanks!

>Solution :

You are mixing bootstrap 4 and 5. I changed this (which is syntax for BS 5):

data-bs-toggle="collapse"
data-bs-target="#toggleMobileMenu"

to this (which is syntax for BS 4):

data-toggle="collapse"
data-target="#toggleMobileMenu"

You can of course go the other direction and switch to BS 5 CDN.
